This is one of many reasons why I think targeted advertising should be regulated or outright outlawed.

Even outside politics, it allows a malicious actor to target their ads to vulnerable targets (whether it’s kids for scammy “games” full of in-app purchases, dubious “medication” for sick & desperate people, or malware to non-tech-savvy people) while flying under the radar of those who would be able to fact-check and call out the scam.
